User Agent: Mozilla/5.0 (Windows NT 6.1; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20100101 Steps to reproduce: Chrome already removed support for secp521r1 curve, Firefox should do the same.
Telemetry also shows that it is used in <0.000002% handshakes, which is a small enough to warrant removal.
